IMPROVED MODE OF SINKING WELL-TUBING.

Specification forming part of Letters Patent No. 58,953, dated October16, 186V.

To all whom it may concern:

Be it known that I, R. F. OsGoOD, of Rochester, in the county of Monroeand State of New York, have invented a new and useful Improvement inSinking \Vell-T\ibii1g; and I do hereby declare that the following is afull and exact desc: iptiou thereof, reference bdng had `to theaccompanying drawings, making part ot' this specification.

Figure 1 is an elevation of the lower end of a section ot' well-tubingprovided with my improvement; Fig. 2, a similar view, but looking atright angles to Fig. 1; Fig. 3, a vertical section of the same; Fig. 4,cross-section in plane :n a", Fig. 1; Fig. 5, cross-section iu plane yy, Fig. 1.

Like letters ot" reference indicate corresponding parts in all thefigures.

My improvement belongs to that class in which the tubing is driven intothe earth by positive force. In some of these devices the end of themain tubing is inelosed in a hol low shank, with a solid point foropening the way. My arrangement involves this feature; but my inventionconsists in the employment of a spiral wing or wings in combination withthe shank and tubing, in such a manner that in the act of driving atendency is imparted to the said shank to turn around, and thus keep theiiuluction-holes always closed, but when in place the said wing or wingshave a tendency to hold the shank in place while the tubing is turned toopen the holes.

As represented in the drawings, A is the main tubing, provided withinduction-holes a a for the admission of water, and B is the hollowshank in which it rests, which is provided with induction holes b b,corresponding in position with those of the main tubing, and also with asolid point, c, for opening the way. These two main parts are held inconnection by a pin, rl, passing through the main tubing and holding intransverse slots j' j' of the shank. These slots are of just such lengththat the pin turning therein will close or unclose the induction-holes.

At a suitable position the shank B is pro vided longitudinally with aspiral wing or wings, h, of slight inclination, pointingin thatdirection to insure the closing ofthe induction'holes as the tubing isbeing driven.

The operation of the device will be at once understood. As the tubing isdriven downward the spiral wing or wings 7i will give a slight turning'movement to the shank in that direction that will keep theinduction-holes a b closed, as shown in Fig. 5. VVhen driven in place,the main tubing is turned aroundin the shank till the pin d strikes theopposite ends of the slots ff, in which position the induction-holes arebrought in coincidence, as shown in Fig. 3, and the water is allowed toenter to be raised by the pump.

Tere it not for the wing or wings, the in* duction-holes could not bekept closed to exclude earth. The employment ot' this device enables meto connect the main tubing with the shank in such a manner that thesimple turning of the tubing when in place will open the holes. Adeviccis alreadyin useiu which the end of the main tubing rests in a hollowshank that covers the induction-holes in driving; but when the tubing isdriven in place, it must be drawn up nearly the length of the shank touncover the holes, which is not only difficult, owing to the greatfriction, but ele-v vates the tubing at the surface, so that thc pumpcannot be easily attached.

In my device it will be seen that the main tubing has to be turned onlythe diameter ot the induction-holes, and it is not elevated at all. Thisarrangement is also more cti'ective than where a cylinder or shortsection of tube is used inside the main tubing to cover the holes, as inIny patent ot' February 20, 1866, in which case, unless the tubing is oflarge size, the water passage is contracted.

Vhat I claim as my invention, and desire to secure by Letters Patent, is

The combination of the spiral wing or wings h with the shank B andtubing A, operating substantially as and for the purpose herein setforth.
